INSECTS INJURING OAK-LEAVES. 185 



258. Endropia textrinaria Grote and Rob. 



The caterpillar was found oa the white oak at Providence, October 7. 

 October 10 it began to spin a thin slight web at the bottom of the breed- 

 ing box, and the pupa appeared October 12. The moth appeared in 

 the breeding box in May. I have captured the moths in the Adiron- 

 dacks at the end of June, where no oak trees were perceived. 



Larva. — The body is rather slender, the head wider than the segment behind, 

 rounded, rather deeply bilobed, swollen on each side of the apex of the clypeiis ; the 

 latter edged with dark brown, forming a V-sIiap^d line on the front of the head. 

 The prothoracic segment is normal, while the mesothoracic segment is much swollen 

 on each side, the rounded swellings connected by a dorsal curved ridge. On the 

 metathoracic segment is a small transverse ridge, next to that on the meso-segment. 

 On the hinder part of the third abdominal segment is a large double dorsal dark knob- 

 like hump. On the sixth is a conspicuous dark transverse rounded ridge, enlarged 

 and higher at each end. The eighth segment has large warts, and there are also large 

 warts on the sides of segments 7 to 10. The supra-anal plate is triangular but short, 

 with four hair-bearing warts above and four at the end. Anal legs large and broad. 

 The short penultimate segment has a trausverse row of eight large warts; these 

 warts are obsolete on the front half of the body. 



The body is of exactly the color of an oak twig, being dark gray shaded with 

 light, and of the same color beneath as above ; while the knotted appearance of the 

 segments behind the head and in the middle of the body assist in the deception, the 

 caterpillar being remarkably like a bit of oak twig. The anal conical dorsal tuber- 

 cles are large and distinct. 



Moth. — In this species the hind wings are distinctly "tailed," not merely sinuated, 

 as in E. viadusaria, while the fore wings are distinctly excavated, but not dentate 

 below the apex, and they are shorter and broader than usual. Fore wings densely 

 mottled and strigated with ocherous-brown ; an inner, curved, pale-brown line, bent 

 outward on the submedian vein, and meeting the outer line, which either runs very 

 near, or if remote, throws out a connecting streak, in the former case forming an oval, 

 with the end resting on the inner margin of the wing. Outer line dusky fawn-brown, 

 oblique, curved outward above and below inward to meet the inner. Beyond, the 

 wing is shaded with ocherous-brown ; this shade sometimes extends to the border of 

 the wing, interrupted by a submarginal row of irregular pale patches proceeding from 

 the broad, apical, diffuse, pale patch. Discal dots black, distinct in both wings. 

 Hind wings like the front pair, the outer line situated in the middle of the wing and 

 nearer the discal dot than usual. Expanse of wings, 1.50 inches. 



259. Paraphia unipunctaria (Haworth). 



Order Lepidoptera ; family Phal.enid^. 



Eating the leaves early in June, a gray span worm 1.40 inch long, sprinkled with 

 blackish dots and short lines, its head and neck a little thicker than the body, each 

 ring with a small squarish white spot above on its hind edge and with two blackish 

 parallel lines on each side of this spot. 



This moth ranges from New England to Texas ; it is said by Fitch to 

 feed on the oak, and by Abbot (in Guenee) to live on the "elm, oak, 

 cournouiller,^^ etc. The Amilapis triplipunctata of Fitch is undoubtedly 

 synonymous with Haworth's species, originally described as an English 

 species.
